So, a couple of days ago, my phone was out of battery, and I didn't charge it until around 12 hours later. When I plugged it in, it wouldn't turn on at all. I have tried taking the battery out and putting it back in, removing the SIM card, removing the SD, using a different USB power adapter and a different cable, nothing has worked. However, when I take the battery out and put it back in the light on the home button flashes. I have an LG Optimus F3, and any help is appreciated. Thanks!
